Perhaps Frank Lloyd Wright's greatest "Prairie style" house and the creation he called his opus. Darwin D. and Isabelle Martin's house was substantially finished in 1905.

2) The Gardener's Cottage

First discussed in 1905, it was the last of six Wright structures added to the complex, in 1909.

3) The Greenhouse

An entirely new addition to the complex, it is a bit smaller than Martin's commercial greenhouse but will also supply flowers and plants for the entire property.

4) The Carriage House

Another long-missing feature brought back to life from Wright's blueprint. It has a garage with a chauffeur's apartment above and a stable to the rear.

5) The Conservatory

One of three demolished structures resurrected under the restoration plan. Martin deemed this gem too small for a year-round "growing house" and added a commercial greenhouse without Wright's approval.

6) The Pergola

This new structure replicates the elegant enclosed walkway that was the north-south spine of Wright's cross-axial design; it connects the main house with the Conservatory and Carriage House. The original was razed years ago.

7) The Barton House

Designed for Martin's sister, Delta, and her husband, this was Wright's first Buffalo building to be completed, in 1904.

8) Floricycle

A semicircular flower bed bordering Summit Avenue completed the Martin House's lateral axis and was meant to contain plants that bloomed successively through the growing season.

9) The Visitors Center

This low-profile $7 million structure designed by Toshiko Mori will be built to the west of the Matin House; it will be the last addition to the complex's footprint.
